摘要
目的探讨Ⅱ、Ⅲ期老年结肠癌患者术后辅助化疗疗效及影响预后因素。方法回顾性收集行结肠癌根治术、术后分期为Ⅱ或Ⅲ期的老年患者(>60岁)临床病理资料及术后治疗资料, 采用Kaplan—Meier法比较术后辅助化疗老年患者和单纯手术老年患者无复发生存(DFS)和总生存(OS), 并按临床分期进行亚组分析。用COX回归模型对可能影响预后的多种因素进行分析。结果全组患者317例, 其中113例患者仅接受手术治疗, 204例患者术后接受氟尿嘧啶类单药或联合奥沙利铂术后辅助化疗。两组患者DFS和OS差异无统计学意义(69.0%比69.6%, P=0.966;69.9%比76.0%, P=0.250)。亚组分析显示Ⅱ期老年患者两组DFS和OS差异无统计学意义(82.3%比82.1%, P=0.959;83.5%比88.4%, P=0.306), 而Ⅲ期老年患者两组DFS和OS均差异有统计学意义(38.2%比58.7%, P=0.02;38.2%比65.1%, P=0.003)。多因素分析显示, T4、N分期阳性、合并脉管瘤栓、术后未予化疗、术前CA19-9升高是影响老年患者生存的独立因素。结论Ⅱ期老年结肠癌术后辅助化疗不改善DFS和OS, Ⅲ期老年患者术后给予辅助化疗能延长DFS和OS。TNM分期、脉管瘤栓、术前CA19-9水平、术后治疗模式是影响老年患者生存的独立因素。
